What is the best practice for setting scrape intervals for Vestiaire Collective?

Vestiaire Collective is an online marketplace where individuals can buy and sell pre-owned luxury fashion. When scraping websites like Vestiaire Collective, you must follow the site's terms of service and be respectful of their web infrastructure. It's important to ensure that your scraping activities do not negatively impact the site's performance or violate any legal agreements.

Here are best practices for setting scrape intervals for a site like Vestiaire Collective:

1. Check the Terms of Service

Before you set up your scraper, you should carefully read the website's Terms of Service (ToS) or terms of use to determine if scraping is permitted. Many sites explicitly prohibit scraping in their ToS, and violating these terms could lead to legal consequences or being banned from the site.

2. Respect robots.txt

Check the robots.txt file of Vestiaire Collective (typically found at https://www.vestiairecollective.com/robots.txt) to see if the site has set guidelines for web crawlers. The robots.txt file may specify which parts of the site can be scraped and suggest a crawl delay to space out requests.

3. Use Rate Limiting

If the robots.txt file or the site's ToS doesn't provide specific guidance on scraping intervals, a good rule of thumb is to be conservative with your scraping frequency. Set a rate limit that mimics human browsing behavior. As a starting point, you might consider one request every 5 to 10 seconds, and then adjust based on server response and other factors.

4. Monitor Server Response

Pay attention to the HTTP status codes you receive from Vestiaire Collective. If you start receiving 429 Too Many Requests or 503 Service Unavailable errors, it indicates that you're sending requests too frequently and should increase your interval between requests.

5. Use Random Intervals

Instead of scraping at fixed intervals, use random intervals between requests to avoid creating patterns that could be easily detected as scraping behavior.

6. Be Polite

Your scraper should not put significant load on Vestiaire Collective's servers. Always prioritize the website's performance and user experience over your data collection speed.

7. Identify Yourself

When scraping, use a descriptive User-Agent string that includes contact information or the purpose of your scraping. This can help the site administrators understand the intent behind your requests.

Here's an example in Python using the requests library to implement a polite scraper with a random delay:

import requests
import time
import random
from fake_useragent import UserAgent

# Generate a random User-Agent
ua = UserAgent()

# Function to scrape with a random delay
def polite_scrape(url):
    headers = {'User-Agent': ua.random}
    response = requests.get(url, headers=headers)

    if response.status_code == 200:
        # Process the data
        pass # Replace with your data processing logic

    # Random delay between 5 to 10 seconds
    time.sleep(random.uniform(5, 10))
    return response

# Example usage
url = 'https://www.vestiairecollective.com/some-product-page'
response = polite_scrape(url)

For JavaScript (Node.js) with axios and a similar random delay:

const axios = require('axios');

// Function to scrape with a random delay
async function politeScrape(url) {
    const headers = {'User-Agent': 'Your Custom User Agent'}; // Replace with a real User-Agent
    try {
        const response = await axios.get(url, { headers });
        // Process the data
    } catch (error) {

    // Random delay between 5 to 10 seconds
    const delay = 5000 + Math.random() * 5000;
    return new Promise(resolve => setTimeout(resolve, delay));

// Example usage
const url = 'https://www.vestiairecollective.com/some-product-page';
politeScrape(url).then(response => {
    // Further processing

Remember to adapt these examples to your specific use case and to handle exceptions and errors appropriately. Always keep in mind that web scraping can be a legally gray area, and it's important to operate ethically and responsibly.
